Organoleads divalent

N. Kano, A Study on Stable Divalent Organolead Compounds, PhD Thesis, The University of Tokyo, 1998. 

Divalent organotin and organolead compounds can be divided into two classes, viz, those in which the organic groups are organic groups are 7r-bonded to the metal. We will deal with these two classes separately beginning with the 7r-bonded species. A third section will cover transition metal stannylene and plumbylene complexes from both classes. 

It was suggested that the lead-promoted reaction involves the formation of an active divalent organolead reagent with the aid of the ammonium bromide, present in solution. A possible structure for the intermediate could be the following ... 

While some of the scientific literature has addressed organolead compounds as environmental contaminants and hazards, the predominant concern is with the inorganic, divalent form and that is the form covered in this book.
